MACHINE FOR REWIN DING PAPER AND OTHER FABRICS.

Specification of Letters Patent.

Patented Feb. is, rare.

Application filed July 30, 1917. Serial No. 183,529.

To all whom it may concern:

Be it known that we, HowAnn B. VANNo'rn and SAMUEL A. NEIDICH, citizensof the United States, residing, respectively, at brouck Heights, countyof Bergen, State of New Jersey, and Edgewater Park, county ofBurlington, State of New Jersey, have invented certain new and usefulImprovements in Machines for-Rewinding Paper and other Fabrics, of whichthe following is a specification.

This invention relates to machines for rewinding paper and otherfabrics.

Our object is the provision of a novel expansible and contractible drum,in a rewinding machine, having means whereby the drum will automaticallycontract in exact proportion to the thickness of the material wound,thereby compensating for the variation in diameter of the drum, with itswindings of paper or fabric, which would otherwise occur and insuringuniform length for the successive sheets comprising the web which iswound upon the drum so that upon subsequent severance, the sheets willall be of the same length. V

Our invention contemplates the provision of means whereby the drum maybe expanded or contracted to bring it to any desired initial diameterand automatic means adjustable at will while the drum is rotating forcontracting the drum in diameter at predetermined times in exactproportion to the thickness of thematerial being wound thereon. Thesurface or periphery of the drum is of such a construction thataccommodation is given for the excess material in the under layers asthe drum contracts and successive windings are placed therearound.

In all forms of ourinvention the drum has a peripheral winding surfacecomposed of a plurality of separated sections or segments which arepreferably slate or bars extending lengthwise of the drum. Thesesections are mounted for outward and inward movement in a radialdirection and novel means are provided for simultaneously and quicklymoving the sections inwardly or outwardlyto thereby evenly expand orcontract the drum.

The sections or segments being separated or spaced apart, the excessmaterial of the paper or fabric which is being wound on the drum formsloops between the opposing faces of the sections as the drum contracts,

thereby taking care of this excess and preventing any bunching of thematerial which would interfere with the evenness of successive windings.

The drum is rotated in any suitable manner, as, for instance, by a belt,and it is mounted on a shaft. Novel means operatively connecting theshaft with the drum provide for the automatic contraction of the drum atpredetermined times, the basic principlebeingthat the drum is expansibleand contractible by changes of relationship between the speed of thedrum and that of the supporting shaft therefor, controlled at will Whilethe drum is rotating.

In the following description there are set forth, and in theaccompanying drawings shown, certain mechanisms or means foraccomplishing the automatic expansion and contraction of the drum in themanner above set forth. We are aware, however, that other means could beused for the accomplishment of this purpose and the disclosure ofcertain means for that purpose is therefore to be considered asillustrative, rather than descriptive, of the scope of the invention.

In the accompanying drawings:

Figure 1 is a side elevation of the invention, shown in connection witha carrier and cutter; i

Fig. 2 a plan view thereof;

Fig. 5 a detail side elevation of the automatic controlling mechanism;

Fig. 6 an elevation thereof with certain parts in section; and

Fig. 7 a detail showing how the layers of paper or fabric form a loopbetween adjacent sections or segments.

In Figs. 1 and 2, the machine of the present invention which appears atthe left, and is generally designated 1, is shown in con nection with acarrier belt, suitably supported, and a paper cutting knife, generallydesignated 2. After the paper has beenrewound on the machine 1, thelayers are cut across by a knife and the bunch of sheets removed fromthe drum and placed on the carrier belt of the machine 2, said beltconveying them to the cutting knife which sev' ers them into properlengths.

The parts of the rewinding machine are supported by a frame 3.. Thepaper or other fabric is carried by a roll 4 which is suitably revolublysupported at 5 so that the web may be freely taken off on to the drum 6.

The drum 6 may be driven by, any suitable means as, for instance, a belt7 passing around the pulley portion 8 and operated from a pulley 9 on asuitably driven countershaft 10. Fixed to the drum 6 are hol lowtrunnions or stub shafts 11 supported in the standards of the frame 3and revolubly supporting the drum as shown in Fig. 6. The drumcomprises, in addition to the heads or parts 6, sections or segments 12which are preferably of wood and are mounted for radial movement, eachsection being carried by stems 13 slidable in boxings or sleeves 14:fixed to the interior of the heads 6 and radially arranged. A shaft 15is mounted in the hollow stub shafts 11 and provided with right and lefthand screw threads 16 and 17. Collars 18 and 19 which are internallyscrew threaded to match the screw threads 16 and 17, respectively, aremounted on said screw threaded parts of the shaft 15 and are connectedto the segments 12 by links 20 and 21 which are pivoted at 22 and 23,respectively. WVhen the shaft 15 is turned in one direction, the collars18 and 19 will approach each other to thereby contract all of thesegments 12 in a uniferm manner thus uniformlydecreasing the diameter ofthe drum. \Vhen shaft 15 is turned in the opposite direction, thecollars 18 and 19 will move away from each other and uniformly expandthe segments 12 to thereby uniformly expand the diameter of the drum.

A crank, not shown, may be applied to the end of the shaft 15 for thepurpose of manually expanding or contracting the drum to bring it to thedesired diameter prior to the winding of the paper or other fabricthereon. When set, the automatic mecha nism, 110w to be described,provides for the automatic contraction of the segments, andconsequently, the diameter of the drum, on each revolution of the drum,with adaptability for changing the adjustment at will while the drum isrotating.

As shown in Fig. 7, the segments 12 are separated by a space 241 whichaccommodates the excess of paper or fabric appearing at 25 of thoselayers 26 which have been wound upon the drum. Consequently, as the drumsuccessively contracts with the additional windings of papertherearound, there is no interference with the smooth and even laying ofthe outermost sheets of paper.

Secured to the stub shaft 11 is a detent disk or wheel 27 which has anotch 28. Fast on the shaft 15 is a'ratchet wheel 29. Pivoted at 30 tothe frame 3 or to a strap 31 carried thereby is a pawl arm 32, actuatedby a spring 33 which draws it toward the ratchet wheel 29 and detentdisk 27. A detent arm 34: having a roller 35 travels on the peripheryof. the disk 27 and once during each revolution of said disk and thedrum 6, enters the notch 28, allowing the pawl arm 32 to engagetheratchet -wheel 29. The depth to which the pawl arm 32 will enter theteeth of the ratchet wheel 29 and the period it will remain inengagement there with is regulated by a thumb screw 36 carried by thearm 32 and arranged in connection with a scale 32*.

Normally, because the shaft 15 is fixed in relation to the segments 12,the ratchet wheel 29 turns with the detent disk27, the roller 35 ridingon the periphery of the disk 27. Once during each revolution of the drum6, the detent roller 35 enters the notch 28, thereby for a predeterminedperiod, enabling the spring 33 to draw the arm 32' forward so that itwill engage ratchet wheel 29. The continued revolution of the drum 6,while the ratchet wheel 29 is arrested, causes the collars 18 and 19 toapproach each other, as they turn on the screw-threaded portions 16 and17, thereby uniformly contracting the segments 12 and decreasing thediameter of the drum 6. The extent of the contraction of the drum isdetermined by the period the roller 35 remains in the notch 28, which,in turn, is regulated by the screw 36. The parts are so timed that thecontraction compensates for the thickness of the paper wound on thedrum, as each succeeding winding is laid thereon. The screw 36 isadapted to be turned while the drum is rotating, if desired, to changethe adjustment. Consequently, it'is not necessary to stop the drum whenadifferent extentof contraction of the drum is'desired. Such change ofcontraction can be had either while the drum is stationary or while itis in rotation.

(larried by the drum is a scale 37, Fig. l, vith which a pointer 38pivoted to a spoke of the drum at 39, coiiperates. A link 40 ispivotally connected to the pointer and to one of the segments 12. Thepointer 38 and scale 37 indicate thecircumferen'ce of the drum at anygiven time.

A suitable clamp, not shown, is usedfor securing one end of the paperto. the drum. A. counting device'or register, not shown, may be used ina well known manner to indicate the number of sheets wound on the drum.I g

A brake may be employed for quickly arresting the drum, as indicated bythe brake beam 11, brake shoe 42 carried thereby and lever 43 foroperating the brake beam.

A. gear train such as shown at 53,. 57, '59, 60 may be used forcontracting the drum shownin Figs. 3 to 7, inclusive. The gears of thistrain may be interchangeable with gears of a slightly different number.of teeth to adjust the rate of amount of contraction of the drum.

The invention may be carried out in other constructions than thatheretofore set forth and shown in the drawings, the principle of theinvention being the automatic contraction of the diameter of the drum bythe employment of means adjustable at will either when the drum isstationary or rotating adapted to periodically change to the desiredextent the relative speeds of the drum and the central controlling shaftas, for instance, by retarding the central shaft as desired once duringeach revolution of the drum.
